Trade tiler lash clips or similar ?

[Yorkshire Tiling Services]

Have been looking at these for ages !! Has anyone used these or similar ? Spoke to David, he says the initial outlay for wedges which are re-useable will eventually make you quids in with time saving getting your tiles bang on level and not having to lift and re-bed.
Always willing to try new products if they are beneficial.
Looked for similar threads here but could not find,sorry if already here somewhere !!
